# Cheat Sheet

## Compile and Run A Snippet Of Code

```c
#include "toy_lexer.h"
#include "toy_parser.h"
#include "toy_compiler.h"
#include "toy_vm.h"
#include <stdlib.h>

int main() {
	//example code
	const char* source = "print \"Hello world!\";";

	//buckets use the arena pattern for memory allocation
	Toy_Bucket* bucket = Toy_allocateBucket(TOY_BUCKET_IDEAL);

	//compile the code
	Toy_Lexer lexer;
	Toy_bindLexer(&lexer, (char*)source);

	Toy_Parser parser;
	Toy_bindParser(&parser, &lexer);

	Toy_Ast* ast = Toy_scanParser(&bucket, &parser);
	unsigned char* bytecode = Toy_compileToBytecode(ast);

	//the ast, which is stored in this bucket, is no longer needed
	Toy_freeBucket(&bucket);

	//the virtual machine used at runtime
	Toy_VM vm;
	Toy_initVM(&vm);
	Toy_bindVM(&vm, bytecode, NULL);

	//execute the given code
	Toy_runVM(&vm);

	//cleanup after ourselves
	Toy_freeVM(&vm);
	free(bytecode);
}
```

## Quick and Dirty Compilation

```c
unsigned char* compileSource(const char* source) {
	Toy_Bucket* bucket = Toy_allocateBucket(TOY_BUCKET_IDEAL);

	Toy_Lexer lexer;
	Toy_bindLexer(&lexer, source);

	Toy_Parser parser;
	Toy_bindParser(&parser, &lexer);

	Toy_Ast* ast = Toy_scanParser(&bucket, &parser);
	unsigned char* bytecode = Toy_compileToBytecode(ast);

	Toy_freeBucket(&bucket);
	return bytecode;
}
```

## API Functions

This is a rough outline of all API functions declared in Toy's headers. As a rule, functions that begin with `TOY_API` are useable and begin with `Toy_`, while functions that begin with `Toy_private_` are generally not intended for use, and only exposed for technical reasons.

*Note: This list is updated manually, if something is outdated let me know.*
